Plants vs. Zombies 2 is celebrating Valenbrainz with a special 13-day event starting today, but that's not all the free-to-play mobile game will have for its user base. With Garden Warfare 2 looming, there's another update incoming, as well.

Shacknews joins the ongoing battle between vegetation and the undead horde with an early look at Plants vs Zombies: Garden Warfare 2. If you thought the first game added a sense of weirdness to team-based battle, just wait until time travel and killer citrus is involved.
